GRASP (Gravitational Radiation Analysis & Simulation Package) is a public-domain software tool-kit designed for analysis and simulation of data from gravitational wave detectors. This users manual describes the use and features of this package.

The rate of gravitational-wave energy loss from inspiralling binary systems of compact objects of arbitrary mass is derived through second post-Newtonian (2PN) order O[(Gm/rc 2) 2 ] beyond the quadrupole approximation. The result has been derived by two independent calculations of the (source) multipole moments. The 2PN terms, and in particular the finite… (More)

The two independent " plus " and " cross " polarization waveforms associated with the gravitational waves emitted by inspiralling, non-spinning, compact binaries are presented, ready for use in the data analysis of signals received by future laser interferometer gravitational-wave detectors such as LIGO and VIRGO. The computation is based on a recently… (More)

We derive the gravitational waveform and gravitational-wave energy flux generated by a binary star system of compact objects (neutron stars or black holes), accurate through second post-Newtonian order (O[(v/c) 4 ] ∼ O[(Gm/rc 2) 2 ]) beyond the lowest-order quadrupole approximation. We cast the Einstein equations into the form of a flat-spacetime wave… (More)

We derive the contributions of spin-orbit and spin-spin coupling to the gravita-tional radiation from coalescing binary systems of spinning compact objects. We calculate spin effects in the symmetric, trace-free radiative multipoles that determine the gravitational waveform, and the rate of energy loss. Assuming a balance between energy radiated and orbital… (More)

(Affiliations can be found after the references in the electronic version) ABSTRACT Aims. A transient astrophysical event observed in both gravitational wave (GW) and electromagnetic (EM) channels would yield rich scientific rewards. A first program initiating EM follow-ups to possible transient GW events has been developed and exercised by the LIGO and… (More)

We present a LIGO search for short-duration gravitational waves (GWs) associated with soft gamma ray repeater (SGR) bursts. This is the first search sensitive to neutron star f modes, usually considered the most efficient GW emitting modes. We find no evidence of GWs associated with any SGR burst in a sample consisting of the 27 Dec. 2004 giant flare from… (More)

Searches for gravitational-wave bursts have often focused on the loudest event(s) in searching for detections and in determining upper limits on astrophysical populations. Typical upper limits have been reported on event rates and event amplitudes which can then be translated into constraints on astrophysical populations. We describe the mathematical… (More)

The finite part of the self-force on a static scalar test-charge outside a Schwarzschild black hole is zero. By direct construction of Hadamard's elementary solution, we obtain a closed-form expression for the minimally coupled scalar field produced by a test-charge held fixed in Schwarzschild space-time. Using the closed-form expression, we compute the… (More)

We derive the gravitational waveform and gravitational-wave energy ux generated by a binary star system of compact objects (neutron stars or black holes), accurate through second post-Newtonian order (O(v=c) 4 ] O(Gm=rc 2) 2 ]) beyond the lowest-order quadrupole approximation. We cast the Einstein equations into the form of a at-spacetime wave equation… (More)
